We know that the formula to find the area of a square is s², where s represents the side length.
Therefore, if the area is 169 m², this is equal to s².
169 = s²
To simplify this, we must perform the inverse operation of squaring a number, which is to square root the number.
√169 = s
13 = s
If the side lengths were 13 meters after being increased by 7 meters, the side length of the original garden is:
13 meters - 7 meters = 5 meters.
Thus, the length of each side of the original garden is 5 meters.
